CFM56-7B sets new world record for time on wing

German airline TUIfly and CFM International celebrated a new first-run time-on-wing world record set by a CFM56-7B engine powering one of the airlines Boeing Next-Generation 737-800 aircraft. The engine logged more than 50,000 hours without a shop visit. The CFM56-7B engine was recently removed for LLP (life-limited part) replacement. Up until its removal, the engine was performing flawlessly and showed very good EGT (exhaust gas temperature) margin. EGT margin is the primary indictor of an engine’s fuel efficiency. The airline has operated a CFM56-powered Boeing fleet exclusively for more than 24 years and currentlyoperates a fleet of 40 CFM56-7B-powered aircraft.
